Realtime APIs today

• One company leads the way:

• Twitter streaming API

• Instagram 'realtime' web hooks API

• ... many more in the works I'm sure...


The enabling technology


1st genPubsubhubub

• HTTP REST based

• Tell provider you want to be pinged every time new content is published

• Best for low frequency

• Popular with blogging and content services


2nd genHTTP Streaming

• Twitter required more

• HTTP Streaming is a one way fire hose

• Efficient and fairly easy to implement


Next genBi-directional socket APIs

• Efficient socket allows both subscription control and data push/streaming

• Next year I predict we will see the first examples

• Why now...?


HTML5 WebSockets

• Now browsers can make bi-directional socket connections.

• We can push data to browsers

• This tech will also be applied to sever comms and APIs


and let the developer community create

Release your realtime data
